This invention relates to warping apparatus wherein a warper receivesits supply of strands from a Creel. The invention is particularlyapplicable to high speed warping apparatus Vwherein the many supplystrands run through the creel under no substantial frictional drag otherthan is caused by unwinding from their supply masses; in this connectionmy invention provides mechanism acting in an improved mannerautomatically to clamp the many strands adjacent to their respectivesupply masses during periods of stoppage of winding. My invention hasfor one of its objects to provide improved mechanism whereby a largenumber of strand clamps can be automatically applied at approximatelythe instant the winding mechanism of the warper ceases to turn, and canbe automatically released at approximately the instant the windingmechanism begins again to turn, In the interim between these operationsthe clamps are adapted to hold the many strands against entanglementshould any of them be brushed or touched by the operator in repairingstrand breakages or in like operati0ns. My invention further provides inits preferred form for avoiding any application of the clamps prior tocomplete stoppage of the winding mechanism of the warper, and any delayin release of the clamp after starting of the winding mechanism to turn.Thus any tensioning of the moving strand is avoided, the clamps servingonly to hold the strands while they are stationary.

Fig. 2 is a plan view of the parts shown in Fig. 1; and

Fig. 3 is a perspective view of one of the upright frame members of thecreel of Fig. 1, showing the arrangement thereon of one of the yarnclamps and a controlling member therefor.

Each side section or half of the frame of the creel preferably includesouter vertical angle irons 11 connected at their tops and bottoms bylongitudinal, horizontal frame members 12 and 13, and inner verticalangle irons 14E connected by like longitudinal memoutwardly projectingbrackets 21.

bers, one of which is indicated at 15 in Fig. 2. Theouter and inner setsof frame members are preferably tied together by transverse members suchas indicated at 16. These transverse members 16 may conveniently eX-tend across and similarly connect corresponding frame members of theopposite side section of the creel, leaving an intervening space orrunway for the operator between the two sections or sides. Since thecreel may be symmetrical, only one of these sections or sides isillustrated.

The inner vertical angle irons 14 conveniently serve as supports forvertically spaced'pins, pegs or spindles 18 adapted to receive unwindingsupply strand packages or rmasses M. From each such mass the unwindingstrand runs to a porcelain eye 18 extending through the correspondingouter angle iron 11. After passing through this eye 18, thestrand runsto the front end of the creel, passing through a guide eye in one ormore Passing from the front of the creel to a warper 8O Or other strandmanipulating apparatus, all of the ends (including usually those fromboth sides of the Creel) are collected into a sheet or web S by anysuitable guiding means, such as a pair of rolls 23, 2-1 and suitablereed 25; this sheet or web as here illustrated runs onto va winding beam81 which is suitably driven by a rotating drum 82 in the warper. Thecontrolling mechanism of the warper may be of any desired type.

Means is provided or clamping each of the many strands in the creel at apoint adjacent to its supply mass. Preferably such clamping means takesthe form of individual clamps, each disposed at the point at which thestrand just leaving its supply mass oins the group of strands leading tothe front end of the creel. In the preferred form of the invention7 sucha clamp utilizes as a stationary or backing member the above-describedporcelain eye 19 (F 3) through which the strand first passes. A movablemember adapted to clamp the strand against this eye 19 preferablyconsists of a circular piece of metal 30 of about the same diameter asthe eye 19. To force the member 30 against the strand extending throughthe eye a light spring 37 fastened to the upright 11 at .32 is arrangedto bear against the rear face of this member 30. The member 30 may besupported by this spring by means of any suitable Connection, preferablya universal tilting connection which insures that the member 30 willseat with certainty on the strand which extends through the eye 19. Asillustrated the member 30 is connected to the spring 37 by a pin 34fastened to the member 30, passing loosely through a hole 35 in thespring, and headed at 36. The spring 37 thus tends to urge the member 30to clamp the strand; during the progress of unwinding the spring 37 andattached member .30 are held away from the eye 19 to permit the strandto pass freely through the eye Without any clamping action.

As part of the controlling mechanism for simultaneously operating theClamps, the Creel preferably includes vertically disposed rotatable rods40, (Figs. 1 and 3) each having a pin 41 projecting therefrom inposition to engage the inner surface of the corresponding spring 37, tomove the spring and member 30 away from the eye 19. As shown in Figs. l,2 and 3, each of the outer vertical angle irons 11 carries one of theserotatable rods, the rod in each case resting on a suitablestep orsupporting bracket 42 which projects from the lower part of the angleiron, and is rotatably held in the corner defined by the two flanges ofthe iron by suitable vertically spaced clips 43. The numerous rotatablerods 40 are preferably bent at their tops to form crank arms 45 whichare engaged by reciprocating rods 50 extending along the top of theCreel. These rods, which may be suitably articulated if necessary, areconnected by a link 51, arm 52 and shaft 53 to an arm 54, so thatmovement of this arm 54 in one direction causes all of the rotatablerods 40 to remove the Clamping members 30 from contact with the guideeyes 19, while movement of the arm 54 in the opposite direction has theeffect of applying all of the clamps of the creel.

For automatically Controlling the Clamps in this manner, the devicepreferably includes detecting means in connection with the warper andadapted to respond to stoppage and starting of the rotation of thewarper, this detecting means preferably taking the form ofspeed-responsive mechanism, for example of the centrifugal-governortype, connected to the warper.

Referring to Fig. 1 such speed-responsive mechanism is shown ascomprising a pair of small weights 84, carried by arms 86 and 87respectively, which are pivotally mounted on a head 88 rotatably driventhrough a shaft 89 and gearing 90 from the main shaft of the warper,turning with the drive roll 82. The arms 86 and 87 carrying the weights84, 85 are connected by links 93 and 94 to a vertically movable sleeve96. rlhese connections are such that upon rotation of the driving drum82 of the warper, the weights 84 and 85 will move outward slightly,causing the sleeve 96 to rise; the reverse operation obviously takesplace upon stoppage. Preferably these parts are suitablycounterbalanced, as by a spring 97 with such delicacy that the sleeve 96responds to slow rotation of the warper drive roll, that is, immediatelythe warper drive roll starts to turn, the sleeve 96 rises. 'The sleeve96 is connected in any suitable manner to a lever 101 pivoted at 102 andin turn connected by a link 103 to the above described arm 54.

lt will readily be apparent that my invention in its broader aspects isnot dependent upon the particular form of the speed responsive device orof the particular nature connections are operated in the reversedirection to apply all of the clamps in the creel, thus securing'all ofthe strands against entanglemcnt.

lt should be understood that the present disclosure is for the purposeof illustration' only and that this invention includes all modificationsand equivalents which fall within thel scope of the appended claims.
